这是一个用java做的网络聊天室

package com.chatroom;

import java.awt.*;

import javax.swing.UIManager;

public class MainChat {
	boolean packFrame =false;
	
	public MainChat() {
		// TODO Auto-generated constructor stub
		ChatFrame frame =new ChatFrame();
		
		if(packFrame){
			frame.pack();
		}
		else{
			frame.validate();
		}
		//设置窗体的摆放位置，将其放在显示器中间
		Dimension screenSize =Toolkit.getDefaultToolkit().getScreenSize();
		Dimension frameSize =frame.getSize();
		if(frameSize.height>screenSize.height){
			frameSize.height =screenSize.height;
		}
		if(frameSize.width>screenSize.width){
			frameSize.width=screenSize.width;
		}
		frame.setLocation((screenSize.width-frameSize.width)/2,(screenSize.height-frameSize.height)/2);
		//将ChatFrame窗体设置为可见
		frame.setVisible(true);
	}
	public static void main(String[] args) {
		try {
			UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
		} catch (Exception e) {
			// TODO: handle exception
			e.printStackTrace();
		}
		new MainChat();
